GAUGE FOR PAPER-CUTTING MACHINES Application filed February 1927. SerialNo. Zl65,7'34ld My invention relates to means for gauging the successivecuts in paper cutting machines,

whereby a quick and accurate adjustment of the paper pile may be made inorder that successive cuts may be at accurate right angles to eachother.

vide a movable and accurately adjustable tion therewith, to provide afixed side gauge for the next successive cut.

at accurate right angles to each other, when the front out has been madeand the paper it so happens that the rear uncut edge of the pile thusturned is not at right angles to the first cut, it is necessary to jogthe pile accurately against the slde gauge. To accomplish this takesconsiderable time and trouto the knife cut.

ble where the side gauge is fixed, and in addition the adjustment maynot be accurate.

It is to remedy this difficulty that my invention is directed, and itconsists of that certain novel construction and arrangement of partswhereby the side gauge may be movable and readily and easily adjustedagainst the paper pile to obtain the desired accurate right angle cutfor the successive operations on the paper.

I have illustrated only so much of the paper cutting machine as may benecessary to explain the construction and operation of the side gauge.

In the drawings Figure 1 is a plan of one corner of the cutting tableshowing the position of the gauges. l Figure 2 is a side elevation ofsame.

Fi ure3is a cross section on the line 3 3 v v a b nation wlth a cuttlngtable, cutting. knife of Fig. 2.

The cutting table is indicated at 1 supportusual back gauge is indicatedat 3, the front edge of which is set accurately parallel to the cuttingknife indicated at 4. This back to gauge slides in the usual grooves inthe table ters Patent is top, and is adjustablein the usual way by theindexed band wheel indicated at 5. y A

The side gauge is set .at accurate right angles to the knife andcomprises a bar 6 which is mounted near. either end on studs 7,

8', 9 and 10. These studs slide in a plate 20, It has been customary inthe past to pro and the studs for each pair are threaded right "and leftand carry gears similarlythreade'd. back gauge for the paper pile, andin connec- The gears 15, 15 and 16, 16 are" held from "longitudinallIlOVQHlGllt'OIl the Screw threaded against which the paper pile is tobe adjusted While the back Y gauge and fixed side gauge have beendisposed studs by hearing plates 11, 12 which are Socured by bolts 13to'the plate 20; The gears are engaged-by a rack bar 17 which extendsbetween each pair, the rackbar being provi'ded with a handle18 extendingout in front pile is given a quarter turn for the second, 1f I inconvenient reach of the operator. It will be obvious fromthisconstruction thatthe rotation of the gears under the action of the"rack bar'will drive the-studs to slide in the plate 20 and adjust theside gauge Outand'in" while maintaining its right angled relation Withthis construction, all the operator has to do when he turns the paperpile for the second cut is to operate the rack bar and bring the sidegaugeup to the cut edge of the pile and the second out will be ataccurate right angles to the previous'cut. v *l/vhile I have shown oneconstruction for adjusting theside gauge, which I prefer, I

do not wish to be limited in the claims that follow to the particularconstruction shown, as other mechanism for adj usting the'fside'gaugewithoutchanging its right angled'relathan to the travel of-thecuttin knife, will fall u u u o t) withln the spirit of my invention.
